MICHAEL S. WELLER, OF OHARLESTOWN, WEST VIRGINIA.

HINGE AND FRAME FOR VAULT-COVERS.

SPECIFECATION forming part of Letters Patent No. 316,705, dated April28, 1885.

Application filed February 13, 1883. Renewed March 17, 1885.

To all whom it may concern:

Be it known that 1, MICHAEL Scorr WEL- LER, a citizen ofv the UnitedStates, residing at Oharlestown, in the county of Jefferson and State ofWest Virginia, have invented certain new and useful Improvements inHinges and Frames for VaultOovers, of which the following is a full,clear, and exact description.

The object of my invention is, first, to conceal the hinge connectingthedoor and its frame, so that no tampering or interfering with said hingeshall be possible, and, second, to so construct the device as to allowthe door to swing back to a given distance and there remain fixed.

My invention consists in the hereinafter-described means for attainingthe said object.

This invention is adapted more particularly to the doors of safes,vaults, and the like, and to cellar and other horizontal doors.

In the accompanying drawings, Figure 1 represents a plan view of myimprovement; Fig. 2, a transverse section of same through lines at 00,Fig. 1; Figs. 3 and 4, detail views.

Similar letters of reference indicate corresponding parts throughout thedifferent views.

A represents the frame of the door, which may be constructed either inwhole or in part of metal. Said frame has formed integral with it orattached to it on either side the boxes at, and said boxes are providedwith slots a in their tops. The outer edges, a of these slots a arebeveled inwardly, for the purposes hereinafter specified, and the boxesa have perforations a in their sides for the journals or pivots a of thehinges.

B represents the doors, and may be of any desired material. Attached tothese doors by bolts or other suitable means are the straps G. Saidstraps are of metal, and are constructed with lugs a formed upon theirunder surfaces some distance from their outer ends, 0. These outer ends,0, are beveled outwardly and downwardly from their edges for the purpose(No model.)

hereinafter specified. The aforesaid lugscare provided with transverseapertures 0, through which the pivots a pass.

The doors being secured to the straps of the hinges, as hereinbeforespecified,the outer ends of said straps are inserted in the slots a. Theapertures a and c are thereby brought into alignment and the pivots ainserted through said apertures. By this means the doors and frames arehinged together. It will now be seen that when the doors are closed thehingelugs c and the pivots a are entirely concealed from View, and anytampering-therewith thus prevented. At the same time the beveled ends ofthe straps are brought flush with the beveled edges of the slots a. Bythis means the introduction of powder or of instruments under the hingesfor the purpose of breaking the same is provided against. When the doorsare opened and thrown back, it will be seen that, on account of thepivot being below the surface of the doors and frame, said doors canonly swing a little beyond aright angle to said frame, and must therestop.

This device is also particularly adapted for cellar and other horizontaldoors, for the reason that by its use a perfectly level surface isexposed, and all danger to pedestrians from stumbling over protrudinghinges, as in ordinary cellar-doors, is avoided.

Having thus described my invention, What I claim is-- it Thecombination, with the doors B, having hinges O, constructedsubstantially as described, of the frame A,provided with boxes a, havingclosed back and sides,and cast integral with said frame, substantiallyas described, whereby the hinge is protected, for the purposes setforth.v
